Special Report on Renewable Energy Sources and Climate Change Mitigation
The Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) of the IPCC Working Group
III provides an assessment and thorough analysis of renewable energy technologies and their current and potential
role in the mitigation of greenhouse gas emissions. The results presented here are based on an extensive assessment of
scientific literature, including specifics of individual studies, but also an aggregate across studies analyzed for broader
conclusions. The report combines information on technology specific studies with results of large-scale integrated
models, and provides policy-relevant (but not policy-prescriptive) information to decision makers on the characteristics
and technical potentials of different resources; the historical development of the technologies; the challenges of their
integration and social and environmental impacts of their use; as well as a comparison in levelized cost of energy for
commercially available renewable technologies with recent non-renewable energy costs. Further, the role of renewable
energy sources in pursuing GHG concentration stabilization levels discussed in this report and the presentation and
analysis of the policies available to assist the development and deployment of renewable energy technologies in climate
change mitigation and/or other goals answer important questions detailed in the original scoping of the report.
